What is the octane rating of avgas?
The octane ratings of AVGAS, a gasoline-based fuel, are usually either 91 or 100 (lean mixture) and 96 or 130 (rich mixture). The octane rating of jet fuel is much lower, around 15 – this is much more like automotive diesel and thus much more resistant to detonating due to sparks or compression.
What does 1 Litre of avgas weigh?
We use approximately 0.7185kg for a litre of Avgas in our calculations.
How many pounds is a gallon of avgas?
Density of avgas (all grades) at 15° C: 6.01 lbs./U.S. gal. Density of avgas (all grades) at -40° C: 6.41 lbs./U.S. gal.
What does 1 Litre of 100LL weigh?
As of January 2010, 100LL has a maximum of 0.56 grams of lead (. 875 gr of TEL) per Litre. This is equivalent to 2.12 grams of lead per US gallon of gasoline.

What is the octane rating of 100LL?
100 octane
Grade 100LL has two milliliters of lead per gallon and is rated at 100 octane when the engine is leaned for cruise, and at 130 octane when the mixture is set at rich. The fuel is designated as “low lead” because the previous fuel with a 100/130 octane rating contained twice as much lead, four milliliters per gallon.
Why is avgas 100 octane?
The most common avgas is 100 octane, which is a measure of the fuel’s ability to resist premature detonation or “knock.” Avgas is also available at other octanes such as 87 and 130, but they are rare today. At the pump, you’ll find gas ranging from 87 to 93 octane for automotive use.
How many liters are in a pound?
Pound to Liter Conversion Table

|---|---|---|
| Water | Cooking Oil | |
| 1 lb | 0.453592 l | 0.515446 l |
| 2 lb | 0.907185 l | 1.0309 l |
| 3 lb | 1.3608 l | 1.5463 l |
Can you run avgas in a car?
Using leaded avgas in a modern car would ruin components such as the catalytic converter. Conversely, Jet-A wouldn’t work in a gas engine.
How much does 100LL avgas weight per gallon?
6.02lbs/gallon.
Is avgas the same as 100LL?
What Are the Differences Between AVGAS 100 and AVGAS 100LL? The key difference between both types is the percentage of the included tetraethyl lead additive. AVGAS 100 has high lead content, while AVGAS 100LL (low lead) includes low amounts of tetraethyl lead, as the name refers.
Can aviation fuel be used in cars?
Jet fuel can actually be used in cars, but only in diesel engines. Kerosene jet fuel and diesel are actually similar enough to allow for cross-functionality and would provide a similar performance. Although, I wouldn’t recommend running a jet on diesel.
What does LL mean in AVGAS 100LL?
Avgas 100LL is a gasoline specially designed for piston engine aircraft. Avgas 100LL is a product blended in refineries which has a blue dye added. “100” is the octane number and “LL” stands for Low Lead content.
What is the highest octane avgas?
They Have Different Octane Ratings
The most common avgas is 100 octane, which is a measure of the fuel’s ability to resist premature detonation or “knock.” Avgas is also available at other octanes such as 87 and 130, but they are rare today. At the pump, you’ll find gas ranging from 87 to 93 octane for automotive use.
Can you run avgas in a race engine?
AvGas is a good gasoline for low speed aircraft engines that run at 2700 to 2800 RPM at 10,000 feet or higher. This does not mean it is a good gasoline for racing engines operating at 8,000 to 10,000 RPM. AvGas is also illegal to use in anything except aircraft engines.
How do you convert liters to pounds?
To convert a liter measurement to a pound measurement, multiply the volume by 2.204623 times the density of the ingredient or material. Thus, the volume in pounds is equal to the liters multiplied by 2.204623 times the density of the ingredient or material.
What does 1 Litre of fuel weigh?
One litre of petrol weighs around 740g but produces around 2.31kg of carbon dioxide when burned. A litre of diesel, which weighs around 840g, produces even more – 2.68kg of carbon dioxide. This CO2 is created in the combustion process in your engine and it’s a potent greenhouse gas.
Why is avgas so expensive?
It’s much higher grade, so it costs more. It’s a specialist fuel made in much less quantities than other fuels, so a premium is added to ensure a profit.
Does avgas go bad?
Studies show with proper fuel management, fuel can be stored for extended periods of time. Military organizations regularly store jet fuel for as long as 36 months with no significant changes to fuel quality specification.
How long will avgas last?
about one year
His question: “What is the shelf life of avgas?” The short answer is that, under most conditions, the shelf life of avgas is about one year.
Why is jet fuel cheaper than gasoline?
Jet A fuel costs less than 100LL (avgas) fuel because it is less complicated and expensive to manufacture, less expensive to transport via pipelines, and used in significantly higher quantities leading to economies of scale.
Can I run 100LL in my car?
Any car will run fine on any gas as long as the octane number is high enough to avoid knocking. But lead destroys the catalytic converter. Otherwise the only problem you may encounter running a car on AVGAS would be when starting the engine in very cold winter weather.
Is avgas 100 still available?
Total disappearance of 100LL without an available 100UL is a real threat to safety. Some airports have banned the sale of all leaded fuel since January 1, 2022, leaving many pilots and aircraft owners without an option that will safely work for their aircraft.
How long is 100LL avgas good for?
The short answer is that, under most conditions, the shelf life of avgas is about one year.
